Pmw Use and Grayson's Book

I don't have Grayson's Tkinter book, but I see he uses something called Pmw.
Why is it needed with Tkinter?

It's not needed. It's just an extra set of widgets that are not
included in the standard set. As I recall, PMW = Python Mega-Widgets.
Check out their site:

http://pmw.source...

You'll probably also come across Tix, another subset of widgets, which
I think is now included with Python be default from 2.4 on up. It
should be noted that PMW is not included with the standard Python
distro though.

I wonder why he uses it? If I want to run his examples, where do I put the
lib he includes? Same folder as the example?

He uses it because Pmw does a lot of heavy lifting for you when
designing Tkinter apps. Pmw adds things like widgets pre-populated
with scrollbars and labels and automatic widget/label alignment. I use
Pmw for all but the most trivial Tkinter applications. That said,
there is nothing in Pmw that you couldn't implement yourself in plain
Tkinter, it's just already been done for you. Check out the Pmw site
for lots of examples and details. Also, if you do install the module,
it comes with a demo directory. Run all.py to see Pmw in action.

Library modules (like Pmw) generally belong in site-packages (/usr/lib/
python2.x/site-packages in most unixes... not sure about windows).

On Windows, most packages go here (adjust as needed for your setup):

C:\Python24\Lib\site-packages
